Product Warranty Obligations
Product Warranty Obligations
We record a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. Most of our products are covered under a warranty period that runs for twelve months from either the date of sale or installation. We also record a liability for specific warranty matters when they become known and reasonably estimable. Our product warranty obligations are included in other current liabilities in the Consolidated Balance Sheet.
